我收到以下错误.也和png和jpeg一起试过,但没有运气..

The file “deleteIt.pdf” could not be opened.
It may be damaged or use a file format that Preview doesn’t recognize.

Answer 1

你倒退了.试试这个

pdf("deleteIt.pdf")
plot(1:10)
dev.off()

启动设备.写信给它.把它关掉.

或者,正如@Spacedman在评论中指出的那样,您可以使用以下内容创建包含当前绘制的任何内容的pdf dev.copy:

plot(1:10)
dev.copy(pdf, "deleteIt.pdf")
dev.off()
